SPOOL-HEAD FASTENER.

To all w/iom, it may concern Be it known that I, \VILLIAM: 13am; nu, a citizen of the United States, and a resident of Yonkers, county of lVestchester, and. State o'l. New York, have invented certain new and useful Improvements in Spooll'lead Fasteners, of which the :l'ollowing is a full, clear, and exact description.

This invention relates more particularly to means for securely and removably lastcir ing the heads of spools, and especially the comparatively large spools employed for holding yarn.

The primary object of the invention to provide simple and ellicient means which is :ulapted to be readily applied to the end or ends of the spool body to rigidly and removably hold the head or heads thereto, at the same time permitting the bearing spindles to rotate with the spool body and head without permitting the heads to be come loose under the strain to which they are ordinarily subjected while in use.

Another object of the invention is to provide tension means which will permit the bearing spindle o-r spindles to be readily placed in position and to lock the spool heads to the body by the use of a wrench or other suitable device applied thereto "for the purpose of securing the head to the end of the spool, and which will permit the head to be likewise detached as well as the remainder of the tension means by rotating the bearing spindle in the opposite direction.

A further object of the invention is to provide simple and efiicient means which may be easily made at a compari tively small cost and readily assembled.

lVith these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is an elevation of a spool showing one form of my invention applied thereto. Fig. 2 is a fragmentary longitudinal section of one end of the spool. F ig. 3 is a t'ansverse section, taken on the line IIIIII of Fig. 2. Fig. 1 is a transverse section, taken on the line I V-IV of Fig. 2, the locking member being shown in elevation. Fig. 5 is a transverse section, taken on the line V-V of Fig. 2. Fig. 6 is Specification of Letters Patent.

a detail perspective of the sleeve member of the tension means; and Fig. 7 is a fragmentary view of part of one of the spool heads.

The body 10 of the spool has a bore 11 at each end which is axially arranged with respect to the said body. In each bore is a sleeve member 12 which held against rotation by a tubular retaining or looking member 13 which extends trai'isversely of the body 10 and passes through an opening 14: in the sleeve member 12.

A. spindle 15 has a bearing portion 16 at one end and for the greater part of its length is threaded, as at 17. The inner end ol the threaded shank or portion of the bearing spindle 15 engages a threaded aperture in a compression nut 18. This nut 18 has diametrically opposed ribs or wings 19 which are adapted to engage slots 20 eX- trnding lengthwise of the sleeve member 12 at the inner end thereof, and interposed between said con'ipression nut and the locle ing member 12:1 is a spring 21 which has a tendency when compressed to force the bearing spindle inward.

The body 10, and at each end thereof, may be provided with a strengthening ring or band 2:? when the body portion is made of wood or similar material. and the outer end of the bore 1.1 is slotted for part of its length, as at 2?), to receive the wings or ribs 21 of a collar or device This device 25 has a central opening through which the threaded shank 17 ot the bearing spindle 15 passes and said device 25 has a collar part 26 adapted to tit over an opening 27 in the spool head 28. The head 28 is flanged, as at 39, for strengthening purposes and has slots, as at 230, which are diametrically opposed and through which the wings Set of the device 25 are adapted to pass to assist in preventing the head from rotating, said win s also engaging slots 30 in the outer end of the sleeve member to prevent rotation of said device. A washer or friction device 31 has a central threaded aperture which is engaged by the threaded shank 17 ot the bearing spindle 15. This washer or device 31. is cup-shaped to adapt the collar portion 26 to rest under the same and has its ring-like surilace adapted to engage the outer surface of the head 28 .in the manner shown.

In assembling the device, the compression nut 18 is first placed within the bore 11 and then the sleeve member 12 may be inserted in such a way that the wings 19 of the compression nut will enter the slots 20 of said sleeve member. The spring 21 may then be passed into the sleeve member so as to rest against the compression nut and then the retaining or looking member 13 placed in position to hold the sleeve mem ber against rotation and form one of the abutments for the spring 21. The head 28 may now be placed in position and the bearing spindle 15 with the friction washer or member 31 and the device 25 arranged thereon also placed in'posit-ion, and the threaded end of the spindle made to engage the threaded aperture of the nut 18. By means of a wrench or similar tool, the spindle 15 may be rotated and in doing so, by reason of the threaded engagement with the washer 31, the latter will rotate with the spindle and cause the compression nut 18 to move outward to compress the spring 21 and thereby tend to force and hold the washer 31 rigidly but frictionally against the outer surface of the spool head 28. The spool head is not only held by reason of the friction device 31, but also by reason of the fact that the wings 24 of the nut or device 25 enter the slots 30 of said head. The reverse action takes place when it is desired to remove the head and other parts of the tension device, and while removing the bearing spindle 15, the washer 31 will remain fixed by reason of the tension of the spring 21 until the nut 18 is released from the spindle, when the said spindle with the device 25 and friction washer 31 may be removed and the remaining parts also removed if so desired.

From the foregoing, it will be seen that simple and effective means is provided whereby the spool heads may be rigidly and removably held to the spool body; that said means is simple in construction and may be readily made and assembled; that efiective locking means is provided to prevent the rotation of the parts except the spindle and washer 23 when applying the tension; and that when tension is properly applied, the said spindle is held against rotation to serve as a bearing for the spool.
